Abstract (en)

[origin: EP3222851A1] The objective of the present invention is to provide a scroll-type fluid machine and maintenance method for same with which reliability and workability are improved by making it possible to supply sufficient grease to necessary parts of an orbiting bearing or auxiliary crank bearing without entailing a complicated operation during maintenance. The present invention provides a scroll-type fluid machine that is provided with a fixed scroll, an orbiting scroll facing the fixed scroll and orbiting, a casing being provided on the outer side of the orbiting scroll in the radial direction, a drive shaft driving the orbiting scroll, an orbiting bearing supporting the drive shaft with respect to the orbiting scroll, and a piping supplying a lubricant to the orbiting bearing, said scroll-type fluid machine being characterized in that: the orbiting scroll is provided with a boss plate that is attached to the drive shaft; the piping is provided in the boss plate; and the tip of the piping faces toward an opening provided between the casing and the fixed scroll or toward an opening provided in the fixed scroll or the casing.
